LOUIS ROSENFELD, OF NEW YORK, N. Y.

ADJUSTABLE LOADING-CHUTE.

SPECIFICATION forming part of Letters Patent No. 7' 09,609, datedSeptember 23, 19 02.

Application filed October 26, 1899. Serial No. 784,844. (No model.)

To ttZZ whom it may concern.-

Be it known that l,'LoUIs ROSENFELD, a citizen of the United States,residing in the city and county of New York, State of New York, haveinvented an Improvement in Adjustable Loading-Chutes; and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to a device which is designed for loading vesselsfrom lighters,

docks, and other places, and where the vessel may be at a veryconsiderable height above the point from which the coal or other cargois to be discharged into the vessel.

It consists of the parts and the construction and combination of partswhich I will hereinafter describe and claim.

Figure l is an end elevation of the device. Fig. 2 is a side elevationof the same.

In the present case I have shown my device as used in connection with alighter or barge by which the coal or other cargo is conveyed to thevessel to be loaded.

A represents such a lighter or barge, and B is a framework of anysuitable height and dimensions properly supported upon the deck. In thedrawings it is so arranged with relation to the batch that the materialcan be raised by means of elevating tackle (shown at G) and adapted toraise the coaltubs to a point directly above the hatch and to asufficient height to discharge the coal.

In order to properly deliver the coal, I have shown the device which isthe object of my present invention. It consists of a chute D ofsufficient length so that its higher end is Within a short distance ofthe line of travel of the hoisting apparatus, and its lower end isextended so as to discharge into a port or through the hatches or otheropenings by which the coal is to be delivered into the vessel which isreceiving it. The angle of the chute is such that the coal will flowfreely by gravitation.

The ends of the chute are supported upon suitable transverse timbers clor framework, which are slidable upon vertical guides or parts of theframe B. As herein shown, the ends of the timbersd are grooved or forkedto straddle or embrace the inner edges of the vertical guides.

The chute or its supporting-timbers is suspended by ropes F, G, and G,these ropes passing over pulleys H and 1, respectively, and beingconnected with the pulley-block J. The fall or tackle consists of ropespassing over the sheaves of this block and other blocks for multiplyingthe power and giving direction to the ropes of the tackle. From theblock K the rope is here shown as leading to a winding-drum L, which isactuated by the hoisting-engine, and the chute having been firstadjusted in its suspension so as to have the proper angle may be raisedor lowered to suit the conditions of tide, the amount of cargo withinthe vessel which would raise or cause it to ride high or low in thewater, and when adjusted to the desired positionit is in readiness toreceive and discharge the material which is to be loaded and which israised by the bucket previously described and delivered into the higherend of the chute, which transfers it overthe intermediate distance tothe point where it is to be delivered, and which may be at a veryconsiderable distance to one side of the line of travel of thehoisting-bucket.

The lower end of the chute is secured to a cross-timber of stirrup d,which is hung from one of the main timbers d by means of straps or rodsG, and the ropes G operate together transversely of the chute overpulleys I and connect to a block or connection at L. The ropes F at thehigher end of the chute operate together over pulleys H and connect toblock J. In addition to the foregoing a block 10 is secured near the topof the frame and another block 12 is secured to the base of the frame,and a rope 13 passes from the block or connection L through the blocks10 and 12 and connect with the block J.

Having thus described my invention, what 'I claim as new, and desire tosecure by Letters Patent, is

The combination of a frame rigidly secured to the deck of a vessel, aninclined chute, one end of said chute resting upon atransverse timberhaving its ends slidable in vertical guides on the frame, the other endof said chute suspended directly from a second transverse timberdisposed in the same horizontal plane with the first timber, and havingits ends; vertically slidable in guides on the asource of power wherebythe chute may be IO frame, ropes attached to each end of saidtimadjusted vertically substantiallyas described.

hers and extending upwardly over pulleys dis- In witness whereof I havehereunto set my posed transversely of the frame, the pairs of hand.ropes at each end of the chute connecting LOUIS ROSENFELD with aseparate block, guide-blocks at top] and bottom of the frame, a roperunning Witnesses:

through said guide-blocks and connecting the A. W. FoLLAUsTEN, twofirst-named blocks, and connections with A. T. FLETCHER.
